Key result
Tumor cell-derived ANGPT2 augments metastatic colonization by protecting melanoma cells from oxidative stress.
Why the study?
ANGPT2 was believed to be exclusively produced by endothelial cells, but scattered reports suggested tumor cells could also be a source.
Population
Patients with melanoma and in vitro and in vivo melanoma models
Comparison
Angpt2 silencing versus control tumor cells, and metastatic versus primary sites
Design
Preclinical experimental and comparative biopsy study

Hypothesis-generating for ANGPT2 targeting in melanoma metastasis; prospective trials required before clinical consideration.
Tumor cell-derived ANGPT2 promotes metastatic colonization in melanoma by protecting tumor cells from oxidative stress, highlighting it as a potential therapeutic target.
Pari et al. (2020) studied Melanoma. Tumor cell-derived ANGPT2 vs. Angpt2-deficient tumor cells was evaluated on Metastatic colonization and oxidative stress response. Tumor cell-derived ANGPT2 augments metastatic colonization by protecting melanoma cells from oxidative stress.
